Embedded JPA Entities are nothing new to the JPA standard. By defining Embedded JPA Entities, you can define a common data type for your application. Unlike regular JPA Entities which generally follow a table per entity mapping strategy. Embedded JPA Entities are stored as additional columns in the underlying relational database table. If you’re using […]Continue reading
In the 1.3.0 release of Spring Boot and new module is available called Spring Boot Developer Tools. This new Spring Boot module is aimed at improving developer productivity in building Spring Web Applications. When you’re developing a web application in Java, or really any programming language, a common workflow is to code, compile, deploy, and then […]Continue reading
Often when using Spring for enterprise application development, while developing code on your laptop, you will want to run against a in memory H2 database, and later you will deploy the code to a server and have it run against enterprise database such as Oracle. While Oracle is the #1 RDBMS used in the enterprise, it’s […]Continue reading
When you start with Spring Boot, it will automatically support H2 if no other data sources have been defined and H2 is found on the classpath. I’ve been using H2 for development for sometime now. It works very well. All modern relational databases are going to support ANSI SQL. But each is going to have […]Continue reading
This is the 4th part of my tutorial series on building a web application using Spring Boot. In the last part of the series, we looked at setting up Spring Data JPA for database persistence. In the second part of the series, we looked at using Thymeleaf for building the web pages. And we started […]Continue reading
Out of the box, Spring Boot is very easy to use with the H2 Database. If the H2 database is found on your classpath, Spring Boot will automatically set up an in-memory H2 database for your use. But what if you want to use MySQL? Naturally, Spring Boot has support for MySQL and a number […]Continue reading
In this post, I’m going to walk you through using Spring Boot to set up a Hello World example using Spring Integration and ActiveMQ. We’ll configure Spring Integration to listen on an ActiveMQ queue. For fun, I’ll use Spock to place a message on the queue, and we can watch Spring Integration receive the JMS […]Continue reading
In the first part of this tutorial series for building a web application using Spring Boot, we looked at creating our Spring project using the Spring Initializr. This handy tool gave us a Spring project to work with, jump starting our development effort by creating the project structure and Maven dependencies for us. In this […]Continue reading
Spring Boot – Making Spring Fun Again I’ve been playing around with Spring Boot again and really like what The Spring Team has been doing. Spring Boot is making Spring fun again. I haven’t had this much pleasure developing Spring Applications since I started learning Grails. One of the things I loved about the Grails framework […]Continue reading
H2 Database Console Frequently when developing Spring based applications, you will use the H2 in memory database during your development process. It’s light, fast, and easy to use. It generally does a great job of emulating other RDBMs which you see more frequently for production use (ie, Oracle, MySQL, Postgres). When developing Spring Applications, its […]Continue reading
